I T 0 all whom itmay concern Be it known thatl, JAMES A. JnnNs'rnoT,

at Jersey City, in the county of Hudson and State of New Jersey, haveinvented certain new and useful Improvements in .WVzttergMeters, ofwhich thp following is a specification, such as will Enable thoseskilled in the art to which it appertains to make and use the same. I

This invention relates to water meters and particularly to devices ofthis class known in the art as piston disk meters, and the object- 7 ofthe invention is to provide lmproved class specified, constructed ashereinafter described and clalmed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, andin which 7 Figure 1 is a central vertical sectionof my improved meter taken through the inlet and outlet ports orpassages; Fig. 2 a partial horizontal section on the line.22 of Fig. l

of the construction broken away;

{with par 3 "afview looking at the outlet side of the inner supplementalcasing of the me er in which the piston disk is mounted and showing adetail of the bottom part of the main casing; Fig. 4: a plan view of thepiston disk which I employ; Fig da perspective view of the packing wedgewhich I employ; and, Fig. 6 a bottom plan view of a beveled gear which Iemploy in connection with the corresponding gear mounted in the pistondisk, both of said gears being shown in section in Fig. 1.

The main casing, shape and form of my improved meter are approximatelysimilar to other meters of this class, and said main casing comprises amain bottom part a and a detachable top parted, and the main bottom parta is provided at one side with an inlet pipe connection a and at theopposite side with an outlet pipe connection a Just inwardly of theinlet pipe connection a? is placed a screen or strainer which extendsinto the top part of the casing, and within the main bottom part of thecasing is placed a detachable supplemental piston disk casmg 0 composedof detachable top and bottom parts 0 and c and between the piston diskcasing and the outlet pipe connection is placed a wedgesh.aped packing03 having an opening d which corresponds with the discharge opening ofthe piston disk casing c.

The bottom part a of the main casing is provided with raised lugs orprojections a on which the supplemental piston disk casmg 0 rests, and.with ,raised bosses a, and the top and bottom parts of said supplementalcasing are provided with laterally extending bosses c and screws 0 arepassed downwardly through the bosses 0* and into the bosseso to securethe supplemental casing a to the main casing of the meter, and thebottom and top parts of the main casing are provided where they abutwith projecting cars a, through which are passed bolts or screws a toconnect the separate parts of i 1 said main casing. Countersunk in thetop part of the supplemental inner casing c is an annular band 6 havinga raised trans verse frame member a and secured to the top part of thesupplemental casing c by screws 6 and the top part a of the main casingis provided with a raised portion a forming a chamber a having a bottoma, and on-which the registering mechanism is mounted, said registeringmechanism being contained in a detachable casing f and being of theusual construction and forming no part of my invention, and all theparts hereinbefore described with the exception of the wedge cl are ofold and well known construction and similar to that employed in what isknown as the \Vorthington disk meter and form no part of my invention. I

The piston disk {1 which is mounted in the central supplemental casing cis provided with a central. ball member 9 mounted in top and bottombearings g and g which are arc-shaped in cross section and formedintegrally with the top and bottom parts 01' said casing a. The pistondisk 9 is shown detached in. Fig. 4 and is provided.

in connection with the piston disk 9 is pro-' chamber and said chamber,agear shaft passing into said provided with a beveled gear which mesheswith the first named gear and the teeth of which are less in number thanthe teeth on said first named gear, the

; adjacent ends of said shafts being beveled "and in contact, and meansfor transmitting the movement of the istering mechanism. 3. In a meterof the class-described, a

gear shaft to the regmain outer casing having inlet and exhaust with thefirst named disk casing mounted in the i'ng and provided with an outlet.port which ports at the opposite sides, a central piston main outercascorresponds with the outlet port of the main outer casing, a rockingpiston disk mounted in said piston diskcasing and having a centralspherical body in which is a radial chamber, a shaft passing radiallythrough one side of said body, a beveled gear se- .cured to said shaftwithin said chamber,

a gear shaft passing intosaid chamber and provided with a beveled gearwhich meshes gear and a ported packing wedge inserted between theoutlets of said main outer and tween. 7 a 4. In a meter of the classdescribed, a

;16th day of February, piston disk casingsto form a water-tightconnection therebemain outer casing having inlet and exhaust ports atthe opposite sides, a central piston disk casing mounted in the mainouter casing and provided with an outlet port which corresponds with theoutlet port 01 the main outer casing, a rocking piston disk mounted insaid piston disk casing and having a central spherical body in which isa radial chamber, a shaft passing radially through one side of saidbody, a beveled gear secured to said shaft withinsaid chamber, and agear shaft passing into said chamber and provided with a beveled gearwhich meshes with thefirst named gear, the teeth of one of said gearsbeing less number than those of the other and-the adjacent ends of saidshafts being beveled and in contact, and a piston disk casings to form awater-tight connection therebetween.

In testimony that I claim the foregoing as my nvention I have signed myname in ported packing wedge inserted 4 between the'outlets of said mainouter and
